## Description

Explain complicated existing behavior using checked state diagrams. Use when asked for a state diagram, to diagram the previous explanation, show a bug or recovery path, compare a proposed fix or existing TLA+ spec, or derive a model from an agreed chart. Generates native Mermaid and a readable terminal fallback; optionally view and explicitly save in MEX Hub.

# MEX statechart

Make behavior easier for a human to understand. Generate only on user intent. If a diagram would obscure the explanation, use a better explanation. A prior agent answer identifies the subject; verify it independently against current code.
